I was thinking of getting a Marklin 39618 (BR 61 in Dark Grey) and adding smoke to it. Looking for the feasibility of doing such a conversion for members that may have the loco. here's an inside shot showing the decoder located below the area where the hole would need to be drilled. Do you think there's enough space for a seuthe #10?

Thanks!
Chuck

Hi Chuck!

It's a plastic or metal covered locomotive?

I would recommend the Seuthe #23 or #28.

That last one only if the space doesn't fits the first - the only difference is the smallest size.

http://seuthe-dampf.de/spur-h0/

Final advice: have some 'insulation' over the decoder...

Cheers,

Walter

Thanks Walter, but I'm trying to find someone who already has the loco. Hopefully they will be able to tell me if there's actually enough room to mount any of the Seuthe units.

I think it's rather odd that Marklin had all this room inside the body and:

1) They didn't design it for a smoke unit in the first place.
And...
2) They mounted the decoder way up in the nose of the engine. Cursing

Yes, understood.

I don't have that locomotive and I'm just guessing the solution. Blushing

Instead of this, I have almost the same situation here: I want to insert a smoke unit on the Märklin 37967.
It don't have "plenty" of room in front, but I always wondered why they don't designed it with the smoke unit...
(also looking for an elegant solution on this case)... RollEyes

I will have a look at my loco tonight for you. Not keen to take it apart just for the sake of it but maybe I will be able to give you some kind of definite, maybe, almost, perhaps answer ThumpUp

Maybe that's the best place.
Keep in mind that it is a loco with three trucks: leading and trailing running axles are a truck each, powered axles are another truck.
When the running axles move to the left, the powered axles will move to the right - and vice versa.

Motor, decoder, and speaker are mounted on the platforms above the running axles - there they do not move.
Anything mounted between the powered axles will either have to be small or will have to move left and right with the powered axles.

Can be done. I assume they didn't prepare the loco for smoke to keep the construction more simple.

Regards
Tom

Tom,

From my experience, the streamlined locos are probably some of the easiest steam locos to convert because of the "room" inside. I'm currently converting a older 3791 BR 03.10 (Grey) to sound. If the decoder was placed between the drivers in a vertical position and the speaker in front of it, I think this would have left the nose area open for a smoke unit. I seems rather odd to me that Marklin would design a steam loco of this size and not be smoke unit ready when they have much smaller locos in their line that have smoke options.

The internals of the BR 61 are much like that of the streamlined BR 05 and not similar to the streamlined BR 03.10. The two former locos have closed skirts while the latter requires big holes in the skirt.
The 03.10 does not have a moveable truck for the powered axles - this simple design requires the holes in skirt, but makes installation of smoke generators more simple.

Take a look at your loco once you got it.
Regards
Tom

Chuck looking at the loco there is enough room but is the room usable ? with a 39... loco type you can't just un-solder the wires and move them somewhere else. and messing around with the fixed wire band I wouldn't risk it. whether or not you can dd a shorter smokeunit only you would know, go to Seuthe.de and have a look at the smaller smoke units and see how long they are, than it is a matter of measuring if a smoke unit can be fitted, the other concern is always the heat the smoke generator creates so you wouldn't want it to sit on top of the decoder.

I've asked my self for years why Märklin hasn't put smoke generators in some of their locos., I'm just converting an older locos BR 38 and fitted a smoke generator and I have done this on many others even with a plastic housing, another loco springs to mind BR 96, BR 78,

Unless you move the whole lot from the front I'd say you've got slim chances. has this got sound ?

Yes John it has sound. If you look at the pic in my initial post, the black box with the two white wires is the speaker. My first thought was to install a smoke unit with the wires extending out the bottom that is the equivalent to the Seuthe #10 and using a miniature connector so it could be separated from the body shell for maintenance purposes. You can see the red (hot) and brown (ground) wire where it could be connected for power. A piece of insulation could be placed between the decoder and the base of the smoke unit if clearance allowed.

The more I think about it, it may just be too much of a headache to be worth it in the end. Unsure

I just think it's irksome for Marklin to design steam engines without the capacity to easily add a smoke feature. The BR38 and BR96 are other good examples of engines not readily available for smoke unit installs.

Märklin's current BR 38.10-40 is prepared for a smoke generator (ever since 2003).
The BR 96 has the space filled with other things.

Thanks Tom for clarifying the info on the BR 38. I was referring to the older version, but it does help to make my point that most engines can be designed (or in this case redesigned) to fit a smoke unit. I'm sure that for small locos like the "glaskasten" it wouldn't be feasible from a production standpoint. I think that if in the future Marklin makes an updated version of the BR 96, it may well be designed to accept a smoke unit.

Hi Chuck

After having a good look at my loco and lifting it's lid, your assessment "too much of a headache to be worth it" is spot on.

There really is very limited space available under the smoke stack. The internal shell height, at the smoke stack, is 25.5mm, the smoker length (marklin 7226, which I think is very similar to the Sleuthe #10) 23mm and then the decoder etc. stick up off the frame by about 16mm. So there really is very little space for you to play with in there.

I have got a photo and will try post it shortly.

Have a look at this thread, there is a photo there with the smoke stack not sitting flush with the body. This might be an option for you to try if you really feel the need to have smoke on this loco.

Thanks Angus, that's just the info I needed. ThumpUp

I agree that there's just not near enough room under the stack area to be able to add a smoke unit without considerable "surgery". Sad

The problem is the Sinus drive and the circuit board needed to operate the motor. Depending on how important it is to you, you could install an SB-Modellbau motor and then a standard decoder will work. It will also run better than the old electronics currently controlling the brushless motor. I think then you could relocate the electronics and have room for the smoke unit.

The motor kit will require a Dremel tool to install, no mill is necessary - "Schwierig-keitsgrad: II".

Thanks for the info.

I wish that the pic of the unit on their website was bigger so I could get a better idea what is involved in the conversion.

They need to post PDFs of the instructions that come with the kits so you can get a handle on what is necessary. My experience with the "II" conversions is you need to use a drum sander on the Dremel tool to remove the tits cast into the frame that locate the Sinus motor. Then the new motor will fit right into the radius cast into the frame. Sometimes you also need to remove material inside the boiler to get necessary clearances.

Ask them if they will email you the instructions. Pierre has always been quite friendly and helpful.
